Sulfur hexafluoride gas (SF6) yog cov khoom siv hluav taws xob siv dav hauv kev lag luam fais fab, siv nyob rau hauv high-voltage switchgear thiab transformers. Txawm li cas los xij, qhov teeb meem ntawm seb cov roj puas muaj tshuaj lom tau muaj teeb meem. Kab lus no yuav tshawb txog cov khoom, daim ntawv thov teb, thiab tej zaum yuav muaj kev phom sij rau tib neeg thiab ib puag ncig ntawm SF6 roj.
Cov khoom ntawm sulfur hexafluoride gas
SF6 yog cov roj tsis muaj xim thiab tsw ntxhiab nrog cov khoom siv tshuaj lom neeg ruaj khov thiab kev ua haujlwm zoo ntawm rwb thaiv tsev. Vim nws qhov ntom ntom ntau dua li huab cua, nws muaj kev ruaj ntseg siab hauv ib puag ncig ntuj. Tsis tas li ntawd, SF6 muaj lub zog hluav taws xob zoo rwb thaiv tsev, ua rau nws yog qhov zoo tshaj plaws insulating roj rau siv hauv cov khoom siv fais fab.
Sulfur hexafluoride roj yog tshuaj lom tom qab ua haujlwm, thiab cov roj sulfur hexafluoride tshiab tsis muaj tshuaj lom.
daim ntawv thov cheeb tsam
SF6 roj yog tsuas yog siv nyob rau hauv high-voltage switchgear thiab transformers rau rwb thaiv tsev thiab arc suppression zog. Nyob rau hauv high-voltage Circuit Court breakers, SF6 yog siv rau rwb thaiv tsev thiab arc extinguishing, uas yuav zoo tiv thaiv cov khoom puas vim arc. Tsis tas li ntawd, SF6 kuj tseem siv rau kev hloov hluav taws xob rwb thaiv tsev thiab cov khoom siv hluav taws xob hauv hluav taws xob xa hluav taws xob.
Muaj peev xwm txaus ntshai
Txawm hais tias SF6 roj muaj qhov kev daws teeb meem qis ntawm chav tsev kub, nws cov khoom decomposition yuav ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv yog tias xau. Tom qab SF6 decomposition, nws tsim qee yam tshuaj lom xws li fluoride, sulfide, thiab sulfur dioxide. Cov tshuaj no muaj qee yam toxicity rau kev ua pa, circulatory, thiab central paj hlwb ntawm tib neeg lub cev. Tsis tas li ntawd, kev tshawb fawb ntxiv tau pom tias qhov ntev mus ntev rau qhov siab ntawm SF6 roj yuav ua rau khaus thiab puas rau ntawm daim tawv nqaij, qhov muag, thiab cov mucous membranes. Yog li ntawd, kev ntsuas kev nyab xeeb nruj yuav tsum tau ua thaum tuav thiab siv SF6 roj los txo cov kev puas tsuaj rau tib neeg.
Kev ntsuas kev nyab xeeb
Txhawm rau kom txo tau qhov ua rau muaj kev phom sij ntawm SF6 roj rau tib neeg thiab ib puag ncig, peb tuaj yeem ua qee yam kev ntsuas kev nyab xeeb. Ua ntej, rau qhov chaw uas siv cov roj SF6, yuav tsum muaj qhov cua zoo thiab qhov chaw tsim hluav taws xob tsim kom tsis txhob muaj roj to thiab sib sau ua ke. Qhov thib ob, cov neeg ua haujlwm yuav tsum tau txais kev cob qhia ua haujlwm kom nkag siab txog cov khoom, kev phom sij, thiab siv cov txheej txheem ntawm SF6 roj. Tsis tas li ntawd, ua raws li kev tshawb nrhiav roj thiab kev saib xyuas cov pa tawm kuj yog ib qho kev ntsuas kev nyab xeeb tseem ceeb, nrog rau kev ruaj ntseg cia thiab tuav txoj hauv kev.
